Would you like to know about settings and calculations of overcurrent and earth fault protection relays on electrical power systems? Would you like to plot inverse time and definite time characteristics of overcurrent and earth fault protection relays on electrical power systems?

This app is an essential tool for electrical power system engineers especially substation protection and control engineers. This app calculates the operation time of the overcurrent and earth fault protection relays according to the setting and the fault current. It also can calculate Time Multiplier Setting (TMS).

This app plots the definite time and inverse time characteristics of the overcurrent and earth fault protection relays. You can enter the data of four overcurrent or earth fault relays in this app, and you can compare them for coordinating.

Features :
* four setting sections
* four stages for each setting sections
* Plotting definite time and inverse time characteristics of the protection relays
* there are 6 themes for this app
* Defining the different type of characteristics of the protection relays
* Saving and loading the settings of the protection relays
* Calculating operating time of the protection relays
* Learning
* Quick help
* Examples

You can set current transformer ratio, P.S, T.M.S, type of Characteristics - DT, SI, VI, EI and etc. For each stage of the protection relays and you can plot all of the characteristics.

It contains the basic concept of the overcurrent and earth fault protection that can be used for the better understanding when working with this app.

You can also use this app to coordinate the overcurrent and earth fault protection relays and compare their operating time with each other. You can save and restore all of your relay settings. You can define different types of characteristics - IEC and IEEE Standards, etc. In each section, You can define the number of stages of the overcurrent and earth fault protection relays and you can enter the desired settings.

There are two examples of the setting and coordinating of the relays that you can use to understand it better. In the Learning section, You can get complete instructional information on overcurrent and earth fault protection relays.

Overcurrent and earth fault protection relay app is continuously under development, with more features yet to come. Any feedback and bug-reports are greatly appreciated. Please email the suggestions and bugs of this app. If something is unclear, be sure to check out the 'Quick Help' and Learning sections as all details are summarized there.

Please support this app by downloading it. If you liked this app, please rate and comment it on google play. Your feedback is important to me. Thank you
